I wonder if they've sorted out the 'soft' side motion rods that were so very bendy on the first batch...
I wonder if they've sorted out the heavy handed users that seemed so adept at mishandling the first batch and bending the rods...

Hopefully Dapol have redesigned the front bogie, which seems to be the root cause of problems with the previous models.
Hopefully Dapol haven't compromised the front bogie mounting design, which more closely resembled the prototype than most previous models...

no redesign required, the bogie pivot post  needs to be extended about 1mm to allow enough vertical clearance so that the bogie does not lift off the track if the leading driving wheels are raise 1mm of the track, this topped the derailments. I proved this soon after the Schools were released originally and posted my fix for this both here and on the Dapol digest.

hope this helps

Perhaps Dapol will shop the new lot with a warning sticker and a pair of kid gloves.

Unless I'm really misunderstanding your meaning, there must be something seriously wrong in the tracklaying (e.g. very large steps or twists) for wheels to be lifter that far above the rail head...  :hmmm:

well probably better than the boxing gloves some modellers would seem to wear to handle their locos...  ;)

A lot of makes of points have edges and drops that really caught them out.
